Question

5. Tanya bought three pigs for 250 each. She sold one at a loss of 10%. At what percent profit
should she sell the remaining two pigs so as to gain 10% in the entire deal?​

Answer 1

Answer:

Cost price of each pig = Rs 250

Total cost price of 3 pigs = 3 × Rs 250 = Rs 750

Profit on the whole transaction = 10% of Rs 750 = Rs 75

Selling price of 3 pigs should be Rs 750 + Rs 75 = Rs 825

Selling price of one pig for the loss of 10% = Rs 250 – 10% of Rs 250 = Rs 250 – Rs 25 = Rs 225

Thus, selling price of the remaining two pigs should be Rs (825 – 225) = Rs 600

Cost price of the two pigs = 2× Rs 250 = Rs 500

Profit on selling two pigs = Rs 600 – Rs 500 = Rs 100

profit % at which remaining two pigs are to be sold =
